CY74FCT2245CTSOCE4

Overview

The CY74FCT2245CTSOCE4 is an octal bus transceiver from the Texas Instruments FCT logic family, housed in a 20-pin SOIC package. It features three-state outputs and operates within a supply voltage range of 4.75 V to 5.25 V. The device supports TTL input and output levels with a propagation delay of 7 ns. It provides a low-level output current of 12 mA and a high-level output current of -15 mA. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Octal bidirectional data transfer capability
• Three-state output configuration for bus isolation
• TTL-compatible input and output voltage levels

Applications

• High-speed data bus architectures
• Memory module interfacing
• I/O port expansion systems

Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the 'C' temperature grade matches application requirements. Ensure the SOIC-20 package dimensions align with PCB layout constraints. Cross-reference the full part number against official TI databases to confirm current production status and availability.

Selection Notes

Select this component when an octal bus interface with TTL compatibility is required. The FCT series offers faster switching speeds compared to standard LS logic. Verify that the 7 ns propagation delay meets system timing specifications. Ensure the 5V operating voltage aligns with the target power supply rails and signal integrity requirements.

Part Context

This device belongs to the CY74FCT2245T series of octal bus transceivers. It serves as a bridge between microprocessors and peripheral devices. The E4 suffix typically denotes environmental compliance. The SOIC-20 package allows for surface-mount assembly. It is designed for applications requiring reliable data transmission across multiple lines simultaneously.
